T 0 all whom/it may concern:

Be'it known that I, l namcE. BUTLER, a citizen of the United States, residing :ati Johnstown, in the county of QOztmbriaand State of Pennsylvania, have invented a new and useful Can-Propeller; and I ldohereby declare the following to be full, clear,aand exact description of the invention, such as a will enable others skilled in theart to which it appertains tolmake and use the same.

This invention relates to a (car. propeller. of an improved nature and design, for jlllUY- ing or propellingjsingle railway cars and the like. l

The principal object of the :invention is the provision of a mechanism:whichmay be applied to the cal-for rotating one of the axles, without. destroying the structure of any part of the car, or without removing any of the. structure, in other words, areplace:

able mechanism 1 a a One of theifeatures of the mechanism is the provisioni of one set of gears operated by a manually operated shaft to Ineshwith .a gear on one of" the axlesso as to drive the axle at one rate of speed infirst starting the car and aftenthe car has been; started the. said set of gears may be thrown outof mesh with the gear onthe axle, and asecoud set thrown in mesh with the gear Oil the axle,.so as to increase the motion of the gear of said axle, which will; increase the motion of the car Wheel.

The invention comprises further lfdill ures and combination of parts, as hereinafter set forth, shown in :the drawings and claimed;

with semi-annular extensions, one extending 1 laterally from each side of each part,;and

when the two parts are fitted to one of the 1 axles 31111 the manner shown, a complete;

annular hub for the gear wheel is formed.

When; the twe parts of the wheel are fitted to one oftheaxles, bolts 9 are passed through the registering cars 10, and are applied with nuts 11. Pins. 12:are threaded through the semi annular extensions, and. into the axle, 1n ordertocause the gear wheel 5 to rotate therewith. e y e Secured to a beam .13 of the truck is a pairl y 1 is journaleda Keyed to the shaft 15 to slide of bracket bearings 14, inzwhioh a shaft 15 thereon is a member il6 constructed with two gears 17 and 18, and an extension 19, which is formedorconstructed with an annular gr0ove20a The gears 17 and 18 are of dif-% isno desire to propel the car forwardly. Mounted lin bearings of the truck frame is a second shaft 22, havinga pair of gears 23 and 24, which rotate with the shaft 22.. The

gear 23 is of smaller diameter than the gear 24! To first start the car in motion,: the 1 member 16 is shifted so that the gear 17 will mesh with. the gears 5 and 23. After motion: has been imparted to the car, the 1 gear 17 is thrown out of mesh with the gear 23, thenzthe member 16 is shifted so that the gear18 will mesh withthe gear 24. In:this manner ;the motion of the car will be .in-:

creasedi A. crank is adapted to be connected to increase the motion ofthe car the gear 17 16 a level-25 mounted inzguides 26 havinga two part fork 27 (the ends of which fork 1 are pivotediat 28 to atwo part collar 29) is providech The two part collar 29 is secured i by the bolts 30 (which: pass through the 1 cars of the=two parts of the collar) in: the

groove 20 of the: member 16, so that the member 16 may rotate freely with the shaft 15. is mounted is providediwith an aperture 31 1 One of the guides in which the lever 25 i to receive a pin 32, which is adapted to enter 1 anyone of the two apertures 33, so as to holdzthe member 16 in shifted positions.

From the foregoing it will be notedthere has been devised a car propeller in which a.

p 75 i ferent d1ameters,and the gear 17 always remains .lIlITlGSll wit-lithe gear on the axle,except when the car is standing still, and there 1 The invention havingbeen set forth, what is claimed as new and useful is 2- 1. An attachable and detachable propel:

ling mechanism for a railway car, comprlsing a detachable two part gear adapted to be fixed to one of the axles of the car, a shaftmounted in bearings of the'car, a

'member keyed to but slidable on the shaft havingtwo gears of different diameters and provided ;,with an annular groove, a second shaft mounted :in bearings of the car and provided with two'gears of difierent diameters, and means having connections. with saidgroov'e for shifting} the member for changing .themeshingof the gears of the first and second shafts 2.
